SASH-LOCK AN D ANTIRATTLER.

SPECIFICATION forming part of Letters Patent No. 667,616, dated February5, 1901.

Application filed December 15, 1900. Serial No 39,979. (No model.)

To 60% whom it may concern.-

Be it known that I, RICHARD COLLINS, a citizen of the United States,residing at Washington, in the District of Columbia, have invented newand usefullmprovements in Sash- Locks and Antirattlers, of which thefollowing is a specification.

This invention relates to certain new and useful improvements insash-looks and antiro rattlers, and is particularly adapted for use inconnection with window-sashes.

The invention aims to construct a device of the above character whichisadapted to prevent the raising of the lower sash, as well as bindingthe sashes within the windowframe in such a manner as to prevent their 4rattling or their movement one toward the other; furthermorgmxonprgvidea device of the above character which shall be extremely sim- 2o ple inits construction, strong, durable, efficient in its use, comparativelyinexpensive to manufacture, and readily and conveniently applied towindow-sashes already in use; and

to this end the invention consists in the novel combination andarrangement of parts herein after mo re specificallydescribedfillustiated in the accompanying drawings, and particularlypointed out in the claim.

In the drawings forming a part of this specification, Figure 1 is avertical sectional view of the two sashes of a window with my improveddevice secured thereto for locking the sashes together, as well as toprevent their rattling. Fig. 2 is a detail perspective view of theantirattling spring. Fig. 3 is a detail perspective view of thelocking-spring.

Referring to the drawings, wherein like numerals of reference indicatecorresponding parts throughout the several views, 1 indi- 0 cates one ofthe vertical rails of the upper sash and to which is secured the upperend of a rectangular leaf-spring 2, whose lower end normally projectsoutwardly from the surface of the rail 1, but is adapted to be forcedback into contact therewith. Secured to the upper side of themeeting-rail 3 of the lower sash by a suitable fastening means, as at3', is the upper end of a rectangular spring 4. The upper end of thespring 4, which is secured to the meeting-rail 3, is bent at an obtuseangle to the remaining portion thereof and terminates at its upper endinto a ridge or stop 5, which is engaged by the lower end of the spring2. The free portion of the spring 4 normally projects outwardly from theside of the meeting-rail 3 and is adapted to engage the meeting-rail 6of the lower sash to prevent the movement of the sashes toward eachother. The spring 2 is termed the lockingspring and the spring 4 theantirattling stop-spring. The springs 2 4 are automatic in their action,for just as soon as the sashes are moved into their closed positionswith the meeting-rails thereof opposite each other the lower projectingend of the spring 2 flies outwardly and engages the stop of theantirattling spring, while the free portion of the latter projectsagainst the meeting-rail 6 and frictionally holds the same to preventrattling of the sashes. The spring 2 not only prevents the raising andlowering of the sashes when in engagement with the stop 5, but alsoprevents the rattling of the lower sash. Therefore by the employment ofthe two springs in the manner shown the lower sash is not only locked,but the two sashes are prevented from rattling.

In order to open the window, it is necessary that the spring 2 be forcedback against the rail 1, as shown in dotted lines, Fig. 1 of thedrawings, when the lower sash is free to be raised and the upper sashlowered, owing to the fact that when lowering the upper sash the freeend of the spring 4 is forced against the meeting-rail 3. The portion ofthe spring 4 which is bent at an obtuse angle, so that when forcing thespring 2 against the rail 1 the former will not engage the upper portionof the spring 4, which would be the case if the spring 4 was bent atright angles to the remaining portion thereof.

Not only does the spring 4 prevent the rattling of the sashes, butthespring 2 also serves to resist not only the raising and lowering of thesashes, but also prevents any movement of the meeting-rails thereoftoward each other, and it is thought the many advantages of my improvedconstruction can be readily understood from the foregoing description,taken in connection with the accompanying drawings, and it will be notedthat minor changes may be made in the details of construction cured toone of the Vertical rails of the upper sash and its lower end projectingfrom said sash and engaging the upper portion of the spring carried bythe lower sash.

In testimony whereof I have hereunto set my hand in presence of twosubscribing Witnesses.

RICHARD COLLINS.
